- `MASTER Gatien.' i I Applica-tion filed IulyG,

My inventionrelatesto. a pjl'aster'gauge,

and has for-an. object to provide means for enabling a quick. leveling vof the first coat or brown coat `of plaster-,fand for assuring uniform thickness'of said brown coat. Anf other vobject is to providea gauge having trznisverselyy extending means at the bot-- tom for covering the joining ends of laths, in

order to prevent bulging and cracking ofthe` face of the stud, whereas previously, there plaster over said joining ends and over the studs. A further object is to' provide a gauge made of sheet metalwith a double body portion having perforations in the top., for receiving fastening nails, and having transverse openings in the body for receiving'plaster to anchor the gauge.y And an# other object is to provide metallic gauge I means which is imbedded and anchored inthe plaster so as to vform reinforcing means therefor 1n case of fire.

Other objects will appear hereinafter.l

The invention consists inthe combinations and arrangements of parts hereinafter lde-4 scribed andv claimed.

The invention will be bestvunderstood byreference'- to the accompanying drawings, f v

`this specification, and in forming av part of Fig. 1 is a fragmentary side elevation of a wall showing my"Y invention mounted in position thereon; o 1 v Fg. 2 is a vertical sectionalA viewtaken on vlineQf-Q ofFig.1; Y v

Fig. 3 is ahorizontal cross sectional view taken on line 3-3 of Fig. 1; l

Fig. 4 isa view of a blank of sheet metal from whichthe gauge is formed; and

Fig. 5 is a side view of the inishedgauge."

The form of construction illustrated coin-` prises a gauge formed from a blanky of sheet metal, asA shown in Figs. 4 and 5 whichis bent or doubled over onV the longitudinal,`

center line 8 to form Ythe doubled body 9, and the metal is `again bentoutwardly from the body on thev line 10 to form transversely and :outwardly extending flanges 11. Perforations 12 are provided in the-,top of the body portion) for receiving fastening nails 13 to extend'throughvthe body portion and through the laths 14, into the studs Anchoring openings 1G are also formed in the body portion for. receiving partof'the first coatvor brown coat 17 of theplaster.

The gauge is provided with its flanges 11 to particularly adapt the same for mounting it over the joint of the laths `on the studding i925.' seriai No. '41;300.

and for covering/the joining jends lof the lathsyf14, asbest-showny in Fig. 3. The flanges 11 are narrowerithan the usualstand'- they` cross the spacing between the laths 14.V The'plastering entersthese'keyways and be-l comes anchored under-the flanges along the were no places fortheplastering on the face of the'studto key, and "much trouble has been experienced heretofore vin that the kplaster would come loose and fall off. TheY flanges and keyways formed between theY flanges and the studprevent bulging ofthe plaster at'said oining ends or'breaking away o therefrom and from the studding, and"l these v flanges also assist in steadying or holding the devicelirmly in position on the laths while y the brown coatis being applied'. The body l)Y v of the gauge is made of the'exact thickness ofthe brown coat, and the finishing coat 1 8 'isplaced over the brown coatv and over Vthe `top ends vofthe gauge to fully cover the gauge, asbest indicated in Fi It is apparentthat this cracking at the joining ends of the laths, and is also J particularly adapted for preventing 3.- j device is par- Y ticularly adaptedrfor'preventing vbulges and` cracks over the-studs, whereverthe gaugem is applied; and it is also apparent that'witli the gauge applied at suitable intervals, pref-A '90 erably over each stud, the plastervof the wall is reinforcedto substantially retain its shape and position during fires, and will thus prevent the breaking up or falling downv ofthe l plaster, and will retain the plaster -in a complete andsolid sheet. 1

lVhile I have illustratedv described.V

'modifications 'as Vcome within the scope ofthe Yappended claims.

' HavingV described `my invention, what I .the preferred form of construction for'car- A' rying my inventionintoefl'ect, this is capable ofvariatiOnand modification without4 departing Yfrom the spirit ofthe invention. 10Q

claim Yas Vnewand desirefto 'secure by Letters Patent is:` y y j Y o l.' laster gauge and anchor f or use in association with studdingjand lathing comprising associated gauge stripsfor determin` ing the` thickness oftheplastering from the'.

studding for forming therewith keyways inV Which to enter and key the plastering, substantially as described.

2. A plaster gauge and'anchor for use in association With-studding and lathing coni-A prising associated gauge strips for determin-y ing the thickness of the plastering from the lathing; base lianges on said strips for resting on the lathing and extending along the studding .for forming therewith keyWays in which to enter and key the plastering; and alined openings in said associated strips for receiving and keying the plastering therein, substantially as described. i

strips holed to receive securing means; a 'i base'ilange on each strip resting on the lathing and extending along Vthe studding for forming therewith k'eyways in whichy to enter and key the plastering; and openings Yin each strip forV receiving and keying Vvthe plastering therein, substantially as described.

In testimony Whereofl have signed myk naine to this specification.
